European standard EN 303-5 is designated to determine the design,
construction, environmental and operational requirements on heating
boilers with solid fuel. Among other things, in the category "solid fuel" includes biomass.
The
model, originally adopted in 1998 apply where solid fuel boilers
(including biomass boilers) with a nominal heat output up to 300 kW
(approximately equal to 1.000.000 BTU / h), with a maximum allowable
operating pressure up to 6 bar and maximum temperature for water to 100 ° C. Facilities such as fireplaces or pellet stoves are not included in the scope of the standard EN 303-5. It should also be noted that a revised version of EN303-5 is expected, logically, by the end of 2012.
In
accordance with EN303-5 two types of construction materials are
suitable for the manufacture of heating boilers: steel and cast iron. According
to the type of fuel used in the boiler sets a minimum wall thickness of
each part of the boiler (ie, the metal sheet). The nominal heat output also affects the thickness of the wall. Additionally, the wall thickness varies from one part of the boiler from the other. Consequently,
different thickness required for walls which come into contact with the
water in relation to the walls of the feed and the combustion chamber
in contact with both water and fire.
The boiler efficiency is defined as the ratio of useful heat given to the water through the boiler to the thermal power. Apparently the reason he always takes values between 0 and 1.
The minimum performance values of a boiler in relation to the class defined by the following equations:For Class 1, the = 47 + 6 · logQ,For Class 2, the = 57 + 6 · logQ,For Class 3, the = 67 + 6 · logQ,
where is the boiler efficiency (in%) and Q is the nominal heat output of the boiler (in kW).
The
interpretation of these equations is that the performance of a boiler
output of 20 kW must be at least 74.8% in order to be classified in the
third class. It
is interesting that, in general, the minimum boiler efficiency as
defined by the European Standard EN303-5 is higher than that specified
in the U.S. by ASME.
In
practice, the individual laws and regulations for the performance of
biomass boilers are stricter than those specified in accordance with EN
303-5. For
example, in Germany only category 3 boilers permitted while in Austria
the only acceptable performance range is between 73 and 83% for
non-automatic boilers and 76-86% for automatic feeding. Similarly, in Switzerland may only use Class 3 boilers.
Searching
for natural shampoo that we can all make our own, I fell randomly on a
page talking about a cleaning technique of hair called "poo free" and a
hit abroad. This technique is used around the world for over 200 years! Essentially the first handmade shampoo with the best results as people are saying the method. This method replaces the shampoo with a mixture of soda. Soda
excellent cleanser known since ancient times for its miraculous
properties, probably came to stay in our cupboards as dominant product!
Said to be the secret of shiny hair Cleopatra!
RECIPE
water as much as needed2 tablespoons of soda6 drops essential oil of your choice (lavender helps in hair growth and strengthening of the scalp)
I put in a container the soda and essential oil and stir. I begin to add small amounts of water until the mixture becomes like mud. Leave for 10 minutes, open the jar, close it and ready!
I use it as shampoo! Well douse my hair and add a small amount of the mixture in my hair. About a teaspoon. I gently massage and rinse out. Simple! The quantity reaches for several washes in long hair.The method in principle seemed funny for efficacy, but as the days go by my hair already big difference! Molded much more easily, more smoothly and hairstyles outwear. Besides,
if you look at the ingredients on the bottle of shampoo you will see
that they consist of soda ((95%), glycerin and fragrances!
A
new method that dramatically improves the properties of low-quality
silicon and promises significant efficiency gains and a corresponding
reduction in the cost of photovoltaic engineers developed by the
University of New South Wales (UNSW) in Australia.The
research team discovered a mechanism for exchange of hydrogen atoms in
order to succeed in fixing flaws in the structure of silicon, by far the
most expensive material used in the manufacture of solar cells."This
method will allow the solar cell manufacturing from cheap low grade
silicon with yields higher than those achieved with expensive materials"
says Stuart Wenham from the School of Engineering of Photovoltaic and
Renewable Energy UNSW.Solar
panels take advantage of the light energy (photons) emitted by the sun
produce electricity through the photovoltaic effect. The majority of cells made from silicon wafers or thin film cells (thin film) of cadmium telluride or silicon.The
average efficiency of conventional silicon cells is 19%, while the top
product yields traded reach 20.1% lower than those obtained in the
laboratory.With the new technique scientists UNSW aspire to achieve efficienciency of 21-23%.Scientists
have known for decades that the hydrogen atoms when inserted in the
atomic structure of silicon correcting flaws and shortcomings, but until
recently had not managed to control the process and to understand in
depth the mechanism.UNSW
scientists have attempted to control the load condition to hydrogen
atoms (positive, negative, neutral) and is forming the hydrogen motion
around the silicon and its reactivity, which is the important factor
correction of imperfections.As
Wenham says "10,000 times improvement over the mobility of hydrogen and
were able to check the chemical ties with impurities and defects in
silicon so as to hibernate."
An air condition that works with solar energyThe
cooling of a space with an air conditioner is expensive and that is why
this is one of the first functions to meet someone thinks just begun to
deal with photovoltaics.portable air conditionBut
soon finds out that economically not attractive at all to try to cover
the operation of an air conditioner with a standalone photovoltaic
system. Let's see why, considering first what stream consumes an air condition:A small air conditioner and even energy class A of 9.000 BTU consumes almost 1.000 Watt per hour of operation (1.000 Wh). So
even for just three hours of use, for example during the three warmest
hours of the day, consumption reaches 3.000 Wh (watt-hours). So
having photovoltaic panels 600 Wp, deep discharge batteries about 600A
and inverter with pure sine power of at least 3.000 Watt. Such a system costs about 4,000 euros but ... And this for just 3 hours of air conditioning!The
only way for air to photovoltaic (relatively low cost) is the selection
of a sufficiently smaller than 9.000 BTU air conditioner, which will
thus consumes less power. But,
as is natural, it is only suitable for very small spaces such as
caravans, boats or cabins some very small rooms of similar size.Such an air conditioner with solar is here. I tried in practice one here will just describe my experience of testing. The specifications on the website of referral ...
The test of a small air conditioner with solar in practiceI
must stress that try to cool an area is a very energy-intensive
process, so should (must) do everything possible to facilitate the air
conditioner does the job ... So:
We care first for shading the area we want to cool (trees, awnings, etc.).
If there are windows which gets sunlight, the scare with a suitable curtain.
Place the outdoor unit in a cool spot with shade.
Careful not exist losses from cracks, open doors, etc.
Avoid using appliances that emit heat into the conditioned space!Once
I realized that we do not have any of these problems the caravan would
become the experiment, I proceeded to install the small portable air
conditioner.
The installationThe
installation of small portable air conditioner with photovoltaic was
more than simple: The small outdoor unit has two removable flat "hooks"
from which you can hang the outdoor unit from a window of the caravan. There are screw holes for permanent mounting, we also have the ability to simply touch it somewhere without a permanent fix ...
small air conditionerConnected to the indoor unit via a flat tire. Is
this level that you can close the window after installing the air
conditioner (leaving a very small opening a few millimeters that can
easily be covered with a special film to windows or other junk
instrument we have available - ie tape). Very handy ...The
indoor unit and is placed in various ways such as our best serve,
bearing in mind that the level of rubber with the vents has a length of
about a half meter.
air conditioning air condition caravan for caravan, boat, small spacesFrom
the above and from the small shape and weight of the two units
(internal and external) is obvious the effort made to ensure that the
air is indeed portable and moved / positioned with ease.The operation of the air conditionerThe photovoltaic system was already installed was enough to support the testing of the air conditioner. If there were, the requirements of the air conditioner to operate three hours are as follows (cost about 1,200 euros):
Solar panel 230Wp about
200A battery deep discharge
Least 800W Inverter with pure sine
Charge regulator 10A/24VI put the socket, press power ON and wait for the result (I admit with some suspicion) ... In less than five minutes but my surprise was evident! The
room with two beds had become so cool that you felt the need to choose a
lower speed fan in the air conditioner (but I isolate this area from
the rest of the caravan closing the sliding door and thereby reducing
the volume of air needed to cool in half) . There were two stairs adjusting air speed and temperature selection four stairs cooling. I
left the second staircase temperature and fan speed and opened the
sliding door to see the result in the entire caravan length 5.50 meters.The
temperature after about 15 minutes dropped significantly, so you can
feel comfortable inside when the outside temperature must have been
around 34 degrees Celsius (unfortunately I forgot to take with me ...
thermometer, so accurate measurements will be added here in the next weekend)!
ConclusionMy own view is to avoid if we conditioners and apply natural methods to cool the house. But
I understand that this is not always possible, and there may be health
reasons mandating the installation of an air conditioner, even for a
time of need ...The
above solution conditioning is not generally the most economical, but
it is the most economical solution conditioning using photovoltaics. In practice, does what it promises, ie cools very well a caravan 5-6 meters. The noise is not large, about works like a fan.If you would recommend? Undoubtedly yes ... if you absolutely must put conditioner! The
installation was easy, gets the job done with the above, the cost is
reasonable and is the only way for a solar air conditioning at a
reasonable cost.
treating diseases with herbsIllnesses
and pain forcing people living in the village, away from scientific
medicine, resorting Therapeutae in nature, which Great organization and
has amazing results for many diseases show. Certainly
the modern pharmaceutical science resorting to natural sanatorium of
herbs and other plants to prepare from these various drugs.
But
man of the village, herbs general uses almost identical or after a
treatment, completely rough and far from laboratories or chemical
effects. Naturally, for any kind of illness or pain using a different herb or plant.Also each type of plant used accordingly either blossom or leaves, the peel of the fruit etc. These parts of the plant produced some ointment or juice or decoction or poultice or powder etc.
Most known herbs used to treat various diseases are:
For coughs: oats, mallow, amaranth, the dragon, heather, thyme, poppy, lettuce and pine.
For anemia: rosemary, spinach, nettle and bramble.
For chickenpox: dill and fennel.
For diarrhea: the neromolocha, Germany, the strawberry, celery, the Tsapournia.
For influenza: rosemary, the lemon and lettuce.
For asthma: the dragon, oregano, clover.
For Bronchial: eucalyptus, onion, lettuce, thyme, asparagus.
For constipation: cucumber, basil, tomatoes, cantaloupe.
For burns: cabbage, lettuce, tomatoes, "fire the sheet."
For stomach ulcers: mallow, the spurge, the root of oak that are Zervos (Sunless) part.
For dizziness: rosemary and basil.
For mumps: ivy, the pikrangouria.
For the monk: onion, cabbage, flomos.
For pertussis: rosemary, ivy, thyme.
For chilblains: onion, potato, celery.
For rheumatism: artichoke, mint, willow.
For the kidneys: wildness and Pusan (whiskers) of corn.
We left to mention last one herb which was used variously and grows near the village in the position called 'went'. This is the rue or rue (ryti the varyosmos as is the official name). From grass and seeds are used to make red dye. Was used as a drug for seizure for the treatment of epileptic et al. But as a spell-using rue, so it is known or phrase: "to exorcise the rue."
Magic - SpellsThe magic, as technical change in natural law, is unknown in the village, even as a concept. As energy but for satisfaction or variation of the desire some people is widespread and manifests itself in various ways. The
used magical means mingled with elements of the Christian religion, as
demonstrated by some spells (incantations), or may even be purely
Christian greetings lined mystic energies and symbols. People who make their magical rituals and exorcisms on behalf of others, not always aimed at payment. However, do not reveal how their energy or words or wishes they say, for fear of losing their own "magical" ability. Spells
and magical rituals are usually the "exorcism" of evil spirits, for the
treatment of human and animal diseases, to prevent magical energy
coming from those who wish evil one, to attract the interest of some
person for some k . LP
Apart
from evil spirits, which cause people turmoil, sickness and disease,
there is a belief that some muscle aches or pains of the body due to the
"pixies" or the "evil eye" (evil eye).
As
a deterrent evil eye are garlic, talisman of earth taken from the altar
of the church, head viper killed on May Day, the amulet of blue beads
and others. Because
not even the fruit trees and fields affected by the spell to protect
them, hang in them the skeleton of the head of an animal, usually the
donkey. The evil eye comes from various people, but mostly by the "smichtofrydides" and monitored by general malaise and headaches. When someone exhibits these symptoms, or resort to "special" village for xematiasma. So
they throw in a glass of water three drops of oil from the lamp of the
house, says the following words: "Holy Mary, dispersed the eye and all
the evils in the woods, the boulders and f 'wild mountains'. These words says it three times and in between studying His name matiasmenou. If the drops of oil diluted, is evidence that the "patient" is still matiasmenos, if not, he has nothing. For
"xematiasma" toddler get flowers from the bier and with the
frankincense incense, or go to church and hold down the Gospel while the
priest reads the Gospel. Also
resort to or "special" for xematiasma and he says these words, after
crucify the child three times: "Blonde cow gave birth and got blonde
calf. He took his mother went to the middle of the bazaar. The saw pazariotes and the evil eye. Togleipse momma and passed. Face, jaw, cheeks "(three times).
Apart from the above spells for xematiasma other spells which are said to cure certain diseases are:
a) For "varvaritses" (hard pimples on the fingers). While the priest says during operation "exairetos the Virgin immaculate ... the person seeking treatment says: To dry the varvaritses me. If this resailed three times then the varvaritses disappear.
b) For the "pasta" (stimulus or pimple in the eye). Sufferer goes to someone who is born to the "alichtisi" to bully ie gafgizontas it as the dog. He
makes the sign of the cross with his hand on the patient's eye and
says: "'Am, um, get Starakis, orzo, because" I am the first child of my
mother and I will eat. "These words are repeated three times.
For
the treatment of mumps, the patient moving his hand up - down slightly
rubbing the part that hurts, saying: The deaf the landlord took the ax
and went deaf to deaf the Logos to bring the deaf wood. Neither root nor HDPE top. " For treating Lugo just go dark at a crossroads (crossroads) with three alatospyra. They take the crossroads three gravel and turning to a road crossed the Lugo with a alatospyro and a pebble. So do to each of the other two paths and each time they say: "'Stars Tonight, tonight Lugo, Taxus nor stars nor Lugo." If you do not go to crossroads, they say: "The Lugo, the pens and t 'grindstone go to town. The Lugo, the pens turned and t 'grindstone lost. . . '. These words are repeated three times the same words to say and treat 'anemopyromatos "rousoumpelis or whatever they call it.
